T0 all whom 'it 'may concern: l

Bc it known that I, Jonas BnoLIN, a itizen of the United States,residing at Dul'uth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements inDecorticatingMachinesg and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relatcsfto decorticating machines', and has for its objectthe provision of an improved machine. for removing shive and waste fromflax fiber, and for other suitable purposes.

It consists of the constructions, combinations and arrangements of partshereinafter described and claimed.

In the drawings, Figure 1 is a diagrammatic view of a portion 'of myinvention, showing' the relation to each other of the materia-l partswhich act directly upon the Hax to be operated upon, such partscomprising conveyers, combs, crushing rolls, and beat- Fig. 2 is a planview of my said. invention, partly broken away. Fig. 3 is a sideelevati-on of one form of my said inveninafter described Crusher rolls.Fig. 11, is an enlarged plan 'View of a portion of said invention,showing means for lifting the hereinafter described upper Crusher rollsto removal of obstructions. Fig. 5 is an en- Fig.- 6 is a rear end viewof said invention.

In the drawlngs, 1 is a frame or support of any suitable construction,in which is spectively, which rolls support a conveyer -belt of anysuitable construction, as 2, for conveying lax straw to respectivelyadjoining parts ofthe mechanism designed to operate upon it. Journaledupon said frame in front of said conveyer belt 2a, which may becalledthe first, primary, or rear oonveyer belt, are a pair of horizontalprimary toothed rolls 4C and 4; respectively adapted to turn oppositelyto each other and draw in between them straw' fed to them lby the firstconveyer belt, and, in a measure, to comb or disentangle the individualstraws from, each other and from various foreign sube.; stances whichmay be mixed with them..l

Next in front of said rolls l1 and 4 is a primary single toothed roll 5,journaled upon said frame and adapted to`further comb said straw as itpasses to the first air of the hereinafter described Crusher ro ls.Partly surrounding said roll 5 and spaced. therefrom is a diaphragm G,supported on said frame, and extending transversely thereof and adaptedto hold the straw close to said roll 5 and to guido it? to the firstpair of said Crusher rolls. Next in front of said roll 5 is a series ofany suitable or desired number of pairs of prima-ry corrugated Crusherrolls, as 7, 8, 9, 10, 11, 12, 13 and 14; each pair comprising an upperand lower roll adapted to receive between them the straw which haspassed the roll 5, the corrugations on each successive pair of saidrolls preferably being finer or sha-llower than on the pair of rollsNext in front one or more pairs of primary smooth crusher rolls, as 15and 16, each pair comprising an upper'and a lower roll adapted t-oreceive between them the straw which has passed the said series ofcorrugated rolls. Beneath the said toothed and corrugated rolls andsmooth rolls is a hopper, 17, preferably supported on said frame andadapted to receive such shive, or other material as may fall between, orfrom any of saidrolls, which hopper is provided with an exhaust port orconduit'18, wherein is located an Vexhaust pan 18a for removing theAcontents -of said hopper. Beneath the .hereinafter described screen 20is a second hopperlSb provided with an exhaust port 18 wherein ispositioned an exhaust Vfan 18d. Next in front of said smooth rolls isatransversely disposed forwardly and downwardly directed apron A,'preferablytformed of angle iron7 and next in front of said apron is arotary beater 19 of, any suitable construction, adapted to beat thestraw as it passes oversaid apron from the smooth rolls. Below saidbeater is a screen 20 adapted to support the straw and guide -it in itsforward course and to screen shive orwaste therefrom. Next forward ofsaid beater, is a rotary primary dofl'er, or detlector 21 journaled onsai'd frame and positioned a little above the hori zontal axial plane ofsaid beater, and ada-pt-V ed to deflect-saidstraw downward after it aspassed said-beater. Next in front of beater,

end of a stock-adjusting or straightenin toothed belt, 23, whichextends'upward an 'a rock shaft and extending aross the rearward face ofsaid adjustinglbelthe office of which comb is to remove excess straw!"from said belt and throw it back into' the hopper Next'in front of'saidstock-adjusting belt and preferably extending at its rearwardy end'beneaththe upper end of said belt, is a second-conve er ,belt` 25, ofany suitable structure, whic ismountedon a pair of rolls 26 and 26@journaled in said frame. Said second conveyerfbelt'is adapted to receivethe' straw and 'fiber as it falls from the stockedjusting belt. Next infr'qnt of said second conveyer belt is a. second L-pair of toothed rollscomprising an upper and a lower roll 27 and 2'7, respectively, whichrolls are adapted to draw between them the straw which is conveyed bysaidfsecond eonveyerbelt and to further comb and straighten it. Nextinfront of said second pair of toothed rolls, is a scc- ,ond toothedsingle roll 28 journaled upon said frame and' adapted to further combsaid straw and fiber as it passes from saidsecond air of toothed rolls.VPartly surrounding said roll 2S, is a'second diaphragm 29, adapt-- edto hold said straw close to said roll 28 and to guide it in its passagetothe first pair of the second series of Crusher rolls hereinrafteridescribed. Next in front of said vsecrespectively,

respectively (the number being reduced-in Fig. 3), each pair comprisingan upper and a lower roll, and the corrugations on each pair4 of rollsbeing finer orshallower than on the pair of rollsnextin the rear in saidseries. Next in front of said second series of corrugated Crusher rollsare one or more. pairs of` smooth crusher rolls, as 35 and 36, each Vofwhich pairs consists of an upper and a lower roll adapted to receivebetween them the straw and ber which has passed said second series ofcorrugated rolls. Beneath said second'pair of toothed of corru ated and'smooth rolls is a 'third hopper 3 adapted to receive the-shive and othermaterial which may fall into it from between said rolls, which hopper isprovided with an exhaust conduit 38 within which is an exhaust fan 38for removing the contents of the hopper. Beneath the hereinafterdescribed screen 42 is a fourth hopper 39 pro- -i'nto which hopperextends the lower he straw andfi er are removed.

vided with' an.. exhaust conduit 39 within which is an exhaust fan 39h.Next in front of said second pair or series of pairs of smooth Crusherrolls-is a second transversely disposed forwardl and downwardly directedapron 40, prefere ly formed of angle iron, and next in front of saidsecond apron is a rotary beater 41 adapted to beat said straw and fiberas it passes over said second apron. Below said'second beater is asecond screen 42 adapted to support the straw and fiber as it passes inits forward course and to screen waste therefrom. Next forward of saidsecond beater, is a rotary do'ifer, or deiector 42EL journaled on saidframe and adapted to deflect said straw and fiber downward after it haspassed thesecond beater, and passes' out of the forward end of themachine. v

The upper Crusher rolls are preferably all journaled eccentrically inrotatable journal bearings 43 which are journaled on said frame, so thatwhen the journal bearings are partly rotated or scillated in onedirection the rolls which are journaledin them will be raise'd and whensaid bearings are oscillated 'in the opposite direction said rolls willbe lowered; thus ythe upper rolls maybe raised to facilitate Acleaningthem or the 'I'.emoval of obstructions. Inorder either to oscillate saidjournal bearings, or to hold them stationary, I provide each` of themwith an, arm, as 43a which may be intgral with the journal bearing asshownin Fig. 4, or which maybe clamped thereto as shown These arms arepivotally con"- nected at their upper ends 'to.connectin, ,1f` rpds, as44. Mounted upon said frame above t e "upper crusher rolls andextendingtrans veiselyof said frame are slidable bars'45 to the ends of whichsaid'connecting rods are coupled by links 46. Engaging said slidable barsand a portion of said frame are screws 47 for operating said slidingbars.

. Driving mechanism of any suitable. construction is provided fordriving the several drive belt wheelV 49' keyed thereto fordrivj ing sai shaft, gears 50 keyed to the axles of the upper crusher rolls, gears51 keyed to the lower crusher rolls and adapted in op eration-to meshwith the gears on said upper rolls, gears 52 keyedl to the' uppertoothed rolls, gears 53 keyed to thelower toothed rolls,v and 'meshinglwith the gears on the upi per toothed rolls, pinioiis 54 keyed to saidtoothed singlerolls, pinions 55 keyed to one of cach pair of conveyerbelt rolls, pinions 56 keyed to the axles of the rotary beatrs, pinions57 keyed tothe vaxles of each of said' doffers or rotary deiiectors, apinion .58 keyed to the axle of one of the rolls 'supporting saidadjusting belt, pinions 59' keyed to the axles of one of each pair ofsaid crusher rolls and to the axles of one of each aus rolls of saidmachine, as a drive shaft 48, a

Til-5 adapted to transmit power from said gears 60 to said pinions, andadrive belt 63. l.

am aware that it is not new to use corra-- gated Crusher rolls, toothedcomb rolls and eonveyer belts for euch purposes. I do not thereforeclaim such construction as broadlyl as might otherwisebe done. The valueof my invention lies in the coinl'iination and arrangement oi.5 theparte which act directly onthe material to be operated upon, whereby acontinuous operation to an elfectual re- Silit iS produced in onemachine which heretofore has required transfer o'l the material from onemachine to .another or to others, at the'expense of much time and labor.I also regard. the aprons A and 40 as particularly valuable and newfeatures of said machine. It is obvious that said construction may bemodified in many particulars within the scope of -my claim; especiallymay it be modified with respect to proportions, dimensions,arrangen'ient of the driving mechaniem, and by the sulistitution otnlerlranical equivalente for certain oi ite parte, l do not thereforedesire to be restricted to the exact proportions, dimensions,arrangements or forms described except as may be specifically requiredby said. claim.
